connect to the OEM Grid Repository and perform the following:

SQL> select target_name from mgmt_targets where target_type=’oracle_emd’;

This command show me the list of all the registered targets from my OEM and I can see that Server1 is still there. Then to manually remove Server1 from the list, I then execute:

SQL> exec mgmt_admin.cleanup_agent(‘Server1:3872′);

exec mgmt_admin.delete_target('PROD','oracle_database');
